Unable to connect aks cluster using github actions, how to fix that?

I am trying to connect to cluster and create a namespace using github actions. For that, I tried these steps.

In the link shared above, I first retrieved the azure service principal for connecting aks.

az ad sp create-for-rbac --name "myApp" --role contributor --scopes /subscriptions/<SUBSCRIPTION_ID>/resourceGroups/<RESOURCE_GROUP> --sdk-auth

And then, proceeded with the steps. But, during namespace creation, I am getting error as below.

W1102 12:06:42.227952 3700 helpers.go:555] --dry-run is deprecated and can be replaced with --dry-run=client.
The connection to the server localhost:8080 was refused - did you specify the right host or port?
Error: Process completed with exit code 1.

Below is the github job failing.
